All 3 Known Issues
The BMW-sourced B58 inline-6 in the A90 Supra develops coolant loss without visible external leaks. The expansion tank cap and electric water pump are common culprits. In some cases, the charge air cooler (intercooler) develops internal micro-cracks allowing coolant into the intake.
Common Symptoms
- Coolant level slowly dropping
- Low coolant warning on dashboard
- No visible external coolant leak
- Sweet smell from engine bay
- White residue around expansion tank cap
How to Fix
Replace expansion tank cap first (BMW 17137640514) - the most common and cheapest fix. Test electric water pump for leaks (BMW 11518632586). If coolant continues dropping, pressure test the charge air cooler for micro-cracks. Upgraded expansion tank caps with higher pressure rating are available from Burger Motorsports.

The ZF 8HP51 automatic transmission exhibits rough or jerky shifts at low speeds, particularly 1st-to-2nd and 2nd-to-3rd gear changes during city driving. The mechatronic unit's valve body can develop wear causing harsh engagement. Cold weather worsens symptoms.
Common Symptoms
- Harsh 1-2 and 2-3 shifts at low speeds
- Jerking during parking lot maneuvers
- Clunking when shifting from Park to Drive
- Shifts improve significantly when transmission is warm
How to Fix
Have dealer perform TCU software update (latest calibration reduces shift harshness). Transmission fluid change with BMW/ZF LifeGuard 8 fluid (83222289720) at 50,000 miles improves shift quality. If mechatronic unit is worn, replacement runs $2,000-3,000. ZF 8HP is generally reliable with proper fluid maintenance.

Early A90 Supras developed rear differential whine under acceleration, most noticeable at 30-60 mph. The electronically controlled limited-slip differential (eLSD) can produce a whining or humming sound from improper gear mesh or bearing preload.
Common Symptoms
- Whining noise from rear under acceleration
- Humming that changes with speed
- Noise louder during hard acceleration
- Noise disappears when coasting
How to Fix
Have dealer inspect differential for proper gear pattern and bearing preload. Toyota issued a software update for the eLSD controller that reduces noise in some cases. Differential fluid change with 75W-85 GL-5 synthetic may help. If gear mesh is incorrect, differential rebuild or replacement under warranty.
